"GNU Screen is a powerful terminal multiplexer that makes it easy for users to manage multiple sessions at the command line. It provides rudimentary window management capabilities in text-based environments and enables users to detach a session and resume it later. The tool has long held a position of distinction among the most popular terminal utilities for system administrators. Although Screen is very powerful, it is also difficult to configure. Most users aren't even aware of its more advanced features and few take advantage of its full potential. In an effort to make Screen more accessible to the masses, the Ubuntu developers have assembled a nice collection of embellishments that make the program easier to configure and use. These improvements are delivered in the screen-profiles package, which was introduced in Ubuntu 9.04."
